GOLDEN RATIO - GOLDEN SECTOR: Also called “Golden Section” or “Golden Section”. Any geometric shape is the proportion that counts as an aesthetic superiority. In the proportion between the parts, the ratio of the small part to the large part is equal to the ratio of the large part to the whole part. Mathematically; a / b = b / (a / b) expression is expressed. The value of the ratio between parts is always 1.618 or approx. 3/5 gets the name "golden number". In black pencil, 1.618 Golden Ratio is geometrically planned as a diagonal of a rectangle consisting of two squares. The Golden Ratio, which has been the subject of mathematicians and art theorists since ancient times, took its place in the 19th century. The Italian mathematician Luca Pacioli divina ratio to this ratio, which the ancient Greeks called a quotient for short; LEONARDO DA VINCI named it sectio aurea. In addition to having arithmetic, algebraic and geometrical features, it is claimed that the Golden Ratio's superiority over all other ratios is due to its unity in diversity, in an environment of close relationship with various ratios existing in nature, music and the organs of the human body. According to some sources, people like proportions closer to the Golden Ratio more.
